<p><P>PROBLEM TO BE SOLVED: To provide a nozzle for a burner enabling easy and secure cleaning of a nozzle hole, and to provide the burner. <P>SOLUTION: A needle 12 having an outer diameter slightly smaller than the inner diameter of the nozzle hole 7 is provided in the nozzle hole 7 of the nozzle 6 so as to enable insertion/removal. The rear end of the needle 12 is coaxially connected to the tip of a coil holder 13, and a coil spring 14 made of bimetal is provided in the coil holder 13. The coil spring 14 is provided in a fuel flow passage within a nozzle holder 5, and is extended/contracted according to fuel temperature. When the fuel temperature is a room temperature, the coil spring 14 is extended so as to insert the needle 12 into the nozzle hole 7. When the fuel is heated, the coil spring 14 is contracted so as to draw out the needle 12 from the nozzle hole 7. By this insertion/removal, cleaning of the nozzle hole 7 is performed. Since this cleaning is performed every time the burner is used regardless of intention of a user, the cleaning can be simply performed without troubling the user. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
